Question

33. Ram and Shyam are travelling
from point A to B, which are
60km apart. Travelling at a
certain speed Ram takes one
hour more than Shyam to
reach point B. If Ram doubles
his speed he will take 30 min-
utes less than Shyam to reach
point B. At what speed was
Ram driving from point A to
B?
(1) 15 kmph
(2) 35 kmph
(3) 30 kmph
(4) 25 kmph
(520 kmph​

Answer 1

Step-by-step explanation:

Let the speed of Ram be 'v' kmph

Time taken by Shyam be 't' hrs

Distance = Speed

×

Time

60 = v (t + 1)

After doubling the speed,

60 = 2v(t - 0.5)

Simplifying them, we get

v (t + 1) = 2v (t - 0.5)

t = 2

v = 60/3 = 20 kmph
