Question

A car travels 135km at a speed of 45km/h and at what speed it travels to cover the distance of 250 km .

Answer 1

Answer:

48.125 km/Hr

Step-by-step explanation:

Car Travels 135 km at a speed of 45 km/hour

Distance = Speed × Time

Time = \frac {Distance}{speed}speedDistance

Time 1 = \frac {135}{45}45135

Time 1 = 3 Hr

Time 2 = \frac {250}{50}50250

Time 2 = 5 Hr

Total Distance = 135 + 250 = 385 km/Hr

Total Time = 3 + 5 = 8 Hrs

Average Speed = \frac {Total Distance}{Total Time}TotalTimeTotalDistance

= \frac {385}{8}8385

= 48.125 km/Hr

average speed =  48.125 km/Hr

Answer 2

Given:-

D = 135km

S = 45 km/h

To Find:-

T = ?

Solution:-

Distance = 135 km

Speed = 45 km/h

$\sf time = \frac{distance}{speed} \\ \\ \sf t = \frac{135}{45} \\ \\ \sf t = 3sec$

next car travel distance = 250 km and time = 3sec. and speed = ?

$\sf speed = \frac{distance}{time} \\ \\ \sf s = \frac{250}{3} \\ \\ \sf \implies83.3 \frac{km}{h}$
