Answer 1

Answer:

70km/hr (as you said)

Step-by-step explanation:

distance  = speed × time

speed = 56km, time = $\frac{5}{2}$hrs

distance = 56 × $\frac{5}{2}$

distance = 28 × 5

distance = 140km

time required = 2 hrs

speed = ?

speed =$\frac{distance}{time}$

speed = $\frac{140}{2}$

speed = 70 km/hr

Hope this helped
