Question

Radha and her 5 friends took part in a marathon relay. they ran a total distance of 42 km and 195 m. if each friend ran 7 km, how far did Radha Run?​

Answer 1

Let the total distance travelled by Radha be x .

Total number of friend = 5

total distance travelled by each friend is 7 km

so,

$\large{\mapsto{x\:+\:7\:×\:5\:=\:42.195}}$

$\large{\mapsto{x\:+\:35\:=\:42.195}}$

$\large{\mapsto{x\:=\:42.195\:-\:35}}$

$\large{\mapsto{x\:=\:7.195\:km}}$

as per our assumption .

that total distance travelled by Radha is x

so total distance travelled by Radha is 7.195 km

Answer 2

Let the total distance travelled by Radha be x .

Total number of friend = 5

total distance travelled by each friend is 7 km

so,

$\large{\mapsto{x\:+\:7\:×\:5\:=\:42.195}}$

$\large{\mapsto{x\:+\:35\:=\:42.195}}$

$\large{\mapsto{x\:=\:42.195\:-\:35}}$

$\large{\mapsto{x\:=\:7.195\:km}}$

as per our assumption .

that total distance travelled by Radha is x

so total distance travelled by Radha is 7.195 km
