Question

Naomi starts running and James starts running 4 seconds later. Let t represent the number of seconds since Naomi started running. Write an expression (in terms of t ) that represents the number of seconds James has been running.

Answer 1

J(t) = t-4

Explanation:

Assuming that both Naomi and James keep on running, the number of seconds that James has been running will always be 4 fewer than the number of seconds that Naomi has been running (t). Therefore, expression (J(t)) that represents the number of seconds James has been running is:

`J(t) = t-4`
