Question

Jada traveled 135 miles in 3 hours.Andre traveled 228 miles in 6 hours.Both jada and Andre traveled at a constant speed

Answer 1

(a) 45 miles

(b) 38 miles

(c) Jada travels faster than Andre.

Explanation:

(a) First we calculate the speed at which Jada travelled:

`Speed = (distance)/(time) \\\\\\s = (d)/(t)`

`s = (135)/(3) \\\\\\s = 45 miles/hour`

Since Jada travels at constant speed throughout the journey, we can calculate the distance traveled in 1 hour:

`distance = speed * time\\\\\\distance = 45 * 1`

distance = 45 miles

Jada travels 45 miles in 1 hour.

(b) We calculate the speed at which Andre travelled:

`Speed = (distance)/(time) \\\\\\s = (d)/(t)`

`s = (228)/(6) \\\\\\s = 38 miles/hour`

Since Andre travels at constant speed throughout the journey, we can calculate the distance traveled in 1 hour:

`distance = speed * time\\\\\\distance = 38 * 1`

distance = 38 miles

Andre travels 38 miles in 1 hour.

(c) Jada travels faster than Andre because he has a higher speed (45 miles/hour) than Andre ( 38 miles/hour).
