Cindy leaves Toronto for Thunder Bay at a steady speed of 100km/h. Two hours later, her brother Bob leaves Thunder Bay for Toronto at a speed of 80km/h. Thunder Bay is 1800km from Toronto.

a) how far will each sibling travel before they meet one another?

b) how much time will each sibling spend on the road before the meet up with one another

Step 1

It is given that, Cindy travel at the steady speed of 100km/h from Toronto to Thunder Bay and two hour later, her brother Bob travel at the speed of 80km/h from Thunder Bay to Toronto.

(a)

Let *x* be the Cindy travel time from Toronto to Thunder Bay and *x*−2 be the Cindy brother travel time from Toronto to Thunder Bay.

Step 2

Also, it is given that, the distance between Toronto to Thunder Bay is 1800km.

Distance between Toronto to Thunder is equal to sum of the distance travelled by each sibling.

Step 3

Obtain the distance travelled...
