8 Darpan runs a distance of 12 km and then cycles a distance of 26 km. His running speed is x km/h and his cycling speed is 10 k
Sonja [21]

The equation in terms of x, for the total time he takes in hours would be 2.48 = 12/x  + 26/10x

<h3>What is speed?</h3>

Speed can be calculated as the ratio of distance traveled to the time taken

Darpan runs a distance of 12 km and then cycles a distance of 26 km.

Total distance = 12 + 26 = 38km

The running speed is x km/h

A = x

The cycling speed is 10 km/h faster than his running speed

B = 10x

He takes a total time of 2 hours and 48 minutes.

So, the total time he takes

Time = Distance x speed

2.48 = 12/x  + 26/10x

10x(2.48) = 120 + 26

24.8x = 146

x = 5.8

Find the unknown number 5/12+()=1/2
xenn [34]

Hello from MrBillDoesMath!

Answer:    1/12


Discussion:

We solve  5/12 + x = 1/2 for x. Begin by subtracting 5/12 from each side

5/12 - 5/12 + x  =    1/2 - 5/12

0                  +x =    6/12 - 5/12      (as 1/2 = 6/12)

So x = 1/12

Regards, MrB
