Let’s solve each problem one by one, step by step. We’ll use multiplication since all these problems involve repeated addition or scaling up quantities.

Problem 1:
If a mechanic repairs 5 cars each day, how many cars does he repair in a week?
→ A week has 7 days.
→ So, 5 cars/day × 7 days =
35 cars
---
Problem 2:
A car factory produces 6 cars every hour. How many cars are produced in 8 hours?
→ 6 cars/hour × 8 hours =
48 cars
---
Problem 3:
Each car has 4 tires. How many tires are there in total for 7 cars?
→ 4 tires/car × 7 cars =
28 tires
---
Problem 4:
A car dealership sells 9 cars every day. How many cars does it sell in a week?
→ 9 cars/day × 7 days =
63 cars
---
Problem 5:
A car race is 7 laps long and each lap is 3 miles long. How many miles is the whole race?
→ 7 laps × 3 miles/lap =
21 miles
---
Problem 6:
A parking lot can hold 8 cars on each of its 6 levels. How many cars can the parking lot hold in total?
→ 8 cars/level × 6 levels =
48 cars
---
Problem 7:
Each car in a rally race uses 4 liters of fuel per mile. How many liters of fuel would a car use for a 10-mile race?
→ 4 liters/mile × 10 miles =
40 liters
---
Problem 8:
A train transports 10 cars each trip. How many cars does it transport in 5 trips?
→ 10 cars/trip × 5 trips =
50 cars
---
Problem 9:
A car factory has 5 production lines, and each line can produce 8 cars a day. How many cars can the factory produce in a day?
→ 5 lines × 8 cars/line =
40 cars
---
Problem 10:
If a car consumes 3 gallons of gas to travel 50 miles, how much gas will it consume to travel 150 miles?
→ First, notice that 150 miles is 3 times 50 miles (because 50 × 3 = 150).
→ So, if it uses 3 gallons for 50 miles, then for 150 miles it will use 3 × 3 =
9 gallons
