Question

The initial odometer
reading is 369 km/hr and
final odometer reading is
477 km/hr in 2hr. Find the
approximation average
speed is
a)14 m/s
b)108 m/s
c)28 ms
d)30 m/s​

Answer 1

I think your question is wrong

Answer 2

Answer:

d)30m/s

Explanation:

Given,

$Initial \:speed(S_{i})=369Km/hr$

$Final\: speed(S_{f})= 477Km/hr$

Time=2hr

$\bold{\boxed{Average \:Speed=\frac{S_{f}-S_{i}}{total\: time}}}$

$Average\: speed=\frac{(477-369)2}{2}$

=108Km/hr

Convert Km/hr to m/s:-

108km/hr

divide by 3.6 to convert into m/s

$average\:speed=\frac{108}{3.6}$

$average\:speed=30m/s$

HOPE THAT HELPS!!
