Question

if distance of travel is 3.5km and time taken=30mins, find speed i) in m/s ii) in km/hr​

Answer 1

speed = 3.5/0.5 = 7 km/hr

speed = 3500/1800 = 1.94 m/s

Answer 2

Answer:

(i) 35/18 m/s

(ii) 7 km/hr

Step-by-step explanation:

Given

• Distance = 3.5 km = 3500 m
• Time = 30 min = 1/2 hr = 1800 s

Now,

We know that,

Distance = Speed × Time

=> Speed = Distance/ Time

Therefore, we will get,

(i) Speed = 3500/1800 = 35/18 m/s

(ii) Speed = 3.5/(1/2) = 3.5×2 = 7 km/hr
