Question

The speed of a airplane is 1,240 km per hour. Find the distance covered by the Airplane3 hour 20 minutes. Also, express the distence in scientific notation

Answer 1

hey mate ....
mark it as a brainlist plz...

the above question uses the formula of :-
distance = speed X time

all the units in the above formula must be in their same units.
so the given values are

speed = 1240 km/hr

Time = 3 hrs 20 minutes =3*1/3 = 10/3 hrs

so now the units are ready for operations.
applying the distance, time and speed formula
we get :-

Distance =
\begin{lgathered}1240 \times \frac{10}{3} km \\ \\ = 413.3333 \times 10 \\ \\ = 413.33 \times 10 \\ \\ = 4.1333 \times {10}^{3}\end{lgathered}
1240×
3
10
​
km
=413.3333×10
=413.33×10
=4.1333×10

here the answer in the scientific notation.
