Question

by travelling at the speed of 28.5 km per hour how much distance will a man cover in 3 hours 48 minutes​

Answer 1

Answer:

108.3 km

Step-by-step explanation:

To find the distance covered by man in 3 hours 48 minutes if 28.5 km per hour is the speed of the man

In 1 hour he travels 28.5 km

In 60 min he travels 28.5 km

(1 hour = 60 min)

in 1 min he travels 28.5/60 km

So, in 48 min he can travels

$= \frac{28.5 \times 48}{60} \\ \\ = \frac{1368}{60} \\ \\ = 22.8 \: km$

In 3 hours he can travel 3×28.5 km

=85.5 km

So, total in 3 hours 48 min that man can travel = 85.5+22.8 km

Distance travel in 3 hours 48 min = 108.3 km

Answer 2

Answer:

Answer:

108.3 km

Step-by-step explanation:

To find the distance covered by man in 3 hours 48 minutes if 28.5 km per hour is the speed of the man

In 1 hour he travels 28.5 km

In 60 min he travels 28.5 km

(1 hour = 60 min)

in 1 min he travels 28.5/60 km

So, in 48 min he can travels

\begin{lgathered}= \frac{28.5 \times 48}{60} \\ \\ = \frac{1368}{60} \\ \\ = 22.8 \: km \\ \\\end{lgathered}

=

60

28.5×48

=

60

1368

=22.8km

In 3 hours he can travel 3×28.5 km

=85.5 km

So, total in 3 hours 48 min that man can travel = 85.5+22.8 km

Distance travel in 3 hours 48 min = 108.3 km
