Question

Brittany drove 320 miles in 4 hours. Lauren drove 280 miles in 4 hours. At these rates, how many more miles can Brittany drive in 5 hours than Lauren?

Answer 1

Answer:

50 miles

Step-by-step explanation:

For Brittany

Brittany drove 320 miles in 4 hours.

4 hours = 320 miles

5 hours = x miles

Cross Multiply

4hours × x = 5 hours × 320 miles

x = 5 hours × 320 miles/4 hours

x = 400 miles

For Lauren

Lauren drove 280 miles in 4 hours.

4 hours = 280 miles

5 hours = x miles

Cross Multiply

4hours × x = 5 hours × 280 miles

x = 5 hours × 280 miles/4 hours

x = 350 miles

At these rates, the number of miles can Brittany drive in 5 hours than Lauren is calculated as:

Number of miles Brittany drives in 5 hours - Number of miles Lauren drives in 5 hours

= 400 miles - 350 miles

= 50 miles
