here ratio=7:5

breadth = 10cm

length=?

now,

or,5x=70

or,x=70÷5

or x =14

so the length of room is 14 cm

A bicyclist traveled with a speed of 12 km/h from a camping ground to a station, located 60 km away. Write a formula expressing

r-ruslan [8.4K]

The bicyclist starts at the camp and travels 12 km/h. So in t hours, the bicyclist travels 12t km. The remaining distance (from the bicyclist to the station) is 60 - 12t, the whole distance, 60 km minus the distance the bicyclist has traveled.

$s=60-12t$

Now you can answer questions such as "how far was the bicyclist from the station after 3 hours?" Substitute 3 for t. s = 60 - 12(3) = 60 - 36 = 24 km.
