Question

Sajal can ride a scooter constantly at a speed of 30km/hr . draw a distance time graph for this situation 1)time taken by sajal to ride 75 km. 2) distance covered by sajal in 3and half hours.​

Answer 1

Answer:

(i) The time taken to ride the d distance 2.5 hours  .

(ii) The distance cover by scooter at speed 30 km/h is 105 km .

Step-by-step explanation:

Given as :

The speed of the scooter = s = 30 km/h

The distance travel by scooter = d = 75 km

Let The time taken to ride the d distance = t hours

According to question

Time = $\dfrac{distance}{speed}$

t = $\dfrac{d}{t}$

∴ t = $\dfrac{75}{30}$

i.e t = 2.5 hours

So,The time taken to ride the d distance = t = 2.5 hours

Hence, The time taken to ride the d distance 2.5 hours  . Answer

(ii) Time taken to cover distance = 3 h + 30 min = T = 3.5 hours

Let Distance cover = d km

Speed of scooter = s = 30 km/h

∵ Distance = speed × time

Or, d = s × T

or, d = 30 km/h × 3.5 h

 ∴  d = 105 km

So, The distance cover by scooter at speed 30 km/h = d = 105 km

Hence,The distance cover by scooter at speed 30 km/h is 105 km . Answer
