To find the inverse of a function expressed as

XXX

an expression in

rearrange the expression into the form:

XXX

an expression in

Given

XXX

−

Switch sides and add

to both sides

XXX

Divide both sides by

XXX

Take the square root of both sides

XXX

√

Since we were asked for an inverse function, I've eliminated the non-primary root (a function can not have two values for a single argument value).

The hare leaps 500 centimeters every 20 seconds. the tortoise crawls 250 centimeters every 50 seconds, but gets a 1000‑centimete

Akimi4 [234]

Time taken for hare to catch up with the tortoise will be found as follows:
time taken=distance/(relative speed)
relative speed=(speed of hare-speed of tortoise)
speed of hare=500/20=25 cm/sec
speed of tortoise=250/50=5 cm/sec
relative speed will be:
(25-5)=20 cm/ sec
thus the total time taken for hare to catch up with the tortoise will be:
1000/20
=50 sec

Answer: 50 sec
