Question

Amol can cover a certain distance in 1 hour 24 minutes by covering two - third of the distance at 4 km/hour and rest at 5 km/hour. Find the total distance travelled ?​

Answer 1

Answer:

6 cm

Step-by-step explanation:

okay so,

total time should be: 1 hour and 24 minutes $1+\frac{24}{60}=1.4 hour$

LET the total distance be x

he travels $\frac{2}{3}x$ of the distance at 4 km/hour.

FORMULA= distance$\frac{distance}{speed} = \frac{2}{3}x\6$ / 4

We are given that the rest at 5 km/hr.i.e.,$\frac{1}{3}x$   of the distance at 5 km/hour.

hence, time=$\frac{1}{3}x\frac{}{6}$

Total time= so,

1.4 = $\frac{2}{3}x/4 + \frac{1}{3}x/5$

1.4=  $\frac{2}{3}x * \frac{1}{4} + \frac{1}{3}x * \frac{1}{5}$

1.4 = $\frac{42}{180} x$

$\frac{1.4 * 180}{42} = x$  

HENCE 6=x and the total distance Amol traveled is 6 cm

HOPE THIS HELPS!!!
