Question

the average speed of a bus is 65 km/hr .the average speed of a car is 26% more than the average speed of a bus .what distance will be covered by car in 12 hours?

Answer 1

Answer:

Step-by-step explanation:

v = d/t

where v = speed, d = distance, t = time

then rearrange

d = v*t

Now substitute

d = 50 * 12 = 780km

Answer 2

Bus Average Speed=65 km/h
Car AVERAGe speed is =26% more than Bus speed
$car \: speed = 65 + (65 \times 26\%) \\ = 65 + (65 \times \frac{26}{100} ) \\ = 65 + 16.9 \\ = 81.9 \: km \: h$
Car AVERAGe Speed=81.9 km/h
Time=12 hours

Distance=Speed× Time
Bus cover Distance=65×12
=780 km

Car Cover Distance=81.9×12
=982.8 km
