Question

Due to inclement weather, the pilot of a plane slows down the plane’s regular flying rate by 25%. This result to an additional 1.5 hours in covering the 3,000km distance to its regular time required for the trip. Find the regular rate of the trip.

Answer 1

Answer:

Normal speed = 711.11 km/h (Approx)

Step-by-step explanation:

Assume;

Normal speed = x

New speed = x - 25% of x = 0.75 x

Time taken = t

New time taken = t + 1.5 hour

Total distance

Computation:

Total distance = 3,200 km

Speed = Distance/Time

x = 3200 / t

t = 3200/x

so,

0.75 x = 3200 / (t+1.5)

0.75 x = 3200 / (3200/x+1.5)

0.75 x = 3200 / [(3200 + 1,5x)x]

x = 711.11 km/h

Normal speed = 711.11 km/h (Approx)
