Question

A train traveling with 70kmph speed covers a distance in 1 1/2 hrs .what is the distance in kms
​

Answer 1

Speed is a scalar quantity, which has a relationship between distance and time.

The formula for speed = distance / time.

First, we collect data:

Speed = 70 km / h

Time = 20 mins

Second, we make sure the unit is uniform.. do the conversion unit:

change time into hour

Time = 20 mins x (1h/60mins) = 1/3 h

Third, we calculate for the distance:

distance = speed x time = 70km/h x (1/3) h =23.33km

Answer 2

Answer:

105 km

Step-by-step explanation:

$speed =$ $\frac{distance}{time}$

$70 = \frac{distance}{1.5}$

$distance = 70 * 1.5 \\ distance = 105 km$
