Answer 1

answer.. 5 days to complete the work

The Average speed of the truck is 100 km/h.

Explanation:-

Given:-

Time taken to cover first 250 km = 2 hours.

Time taken to cover next 350 km = 4 hours.

To Find:-

The average speed of the truck.

Formula Used:-

\large\blue{ \longrightarrow \boxed{ \pink{ \bf s = \frac{d}{t}.}}}⟶

s=

t

d

.

Where,

s = Average Speed.

d = Total distance.

t = Total time.

So Here,

s = ?? [To Find].

\tt d = 250\:km+350\:km = 600\:km.d=250km+350km=600km.

t = \tt 2\:h+4\:h = 6\:\:Hours.2h+4h=6Hours.

Now,

By putting the above values in the formula we get,

\begin{gathered}\\ \bf\mapsto s = \frac{d}{t} .\end{gathered}

↦s=

t

d

.

\begin{gathered}\\ \tt\mapsto s = \frac{600 \: km}{6 \: h} .\end{gathered}

↦s=

6h

600km

.

\begin{gathered}\\ \tt\mapsto s = \frac{100 \: km}{h}.\end{gathered}

↦s=

h

100km

.

\large\red{ \longrightarrow \boxed{ \orange{ \bf s = 100 \: km/h.}}}⟶

s=100km/h.

Therefore The Average Speed Of The Truck Is 100km/h or 100 kmph (Kilometer per hour).
