Answer 1

If the speed of a woman is 15 km per hour, then what is the distance traveled by her in 90 seconds ? 1.375m 2.275m 3.500m 4.475m

Step-by-step explanation:

the answer is 3.500m

Answer 2

Given,

The speed of a woman = 15 Km/hr

To find,

The distance traveled by her in 90 seconds.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

speed (s) = distance traveled (d)/time of journey(t)

=> Distance traveled (d) = speed (s) × time of journey(t)

Now,

The distance traveled by the woman in 90 seconds

= speed (s) × time of journey(t)

= 15 Km/hr × 90 s

= 15 Km/hr × (90/3600) hr

{Since 1 second = 1/3600 hrs}

= (15×90/3600) Km

= 3/8 Km

= 0.375 Km = 375 meters

{Since 1 Km = 1000 m}

Hence, the total distance traveled by the woman in 90 seconds is equal to 375 meters.
