Question

A car drives 207 miles in 3 hours. At this speed, how far will the car travel in 5.6 hours?

Answer 1

Answer:

386.4 miles

Step-by-step explanation:

Given the car travels 207 miles in   3 hours

                                 therefore its speed = $\frac{Distance}{Time}$

                                                                  = $\frac{207}{3}$

                Using the same formula DISTANCE = TIME * SPEED

                                                                    = 5.6 * $\frac{Distance}{Time}$

                                                                    = 386.4 miles

Answer 2

Ans :- 386.5 (ans)

*Speed is the distance travelled per unit time.

GIVEN :-

Distance = 207miles

Time = 3 hrs

Speed = ?

$Speed = \frac{distance}{time} \\ \\ = \frac{207}{3} = 69 miles/hr$

TO FIND :-

Distance covered by the same speed in 5.6 hr

Distance = Speed ×time Time

= 69miles/hr × 5.6 hr

= 386.5 miles. [ANS]

N.B.

$\bf{Here \: we \:havenot \:change \:unit \:of \:speed\: into\: km/hr\: but \:we \:use\: miles/hr}.$
