Who traveled farther?

Question

1.) If mia rides her bike at 14 miles an hour for 1.5 hours and Chloe drives her car at 35 miles per hour for 45 minutes, who travels farther?

 

2.) Would the person who has gone the shorter distance in question 1 be able to catch up within 30 minutes if the other stops?

Answer 1

Mia

d=r*t

d=14*1.5

d=21 miles

 

Chloe

d=r*t

d=35*(3/4)

d=35*0.75

d=26.25 miles

 

Chloe travels farther.

 

Mia

d=r*t

d=14*(1/2)

d=7 miles

d=21+7=28 miles

Yes, the slower person will be able to catch up in 30 minutes.

The slower person could catch up in 22.5 minutes.

d=r*t

26.25-21=5.25

5.25=14*t

t=5.25/14=0.375 of an hour which is 0.375*60=22.5 minutes
