Q12. answer the following questions:
application a) the equation that converts a distance in m
at converts a distance in miles, m, to kilometres, k, is k = 1.6m.
a the equation that converts a distance in kilometres to miles.
b) the length of time, t, in minutes, that jane and
of time, t, in minutes, that jane and her dog bowie spend at the local park is given by
t = 30 + 5d, where d is the number of other dogs at the park.
10. des, wants to deduce the number of dogs jane and bowie encounter from the
amount of time they spend at the park.
rearrange t = 30 + 5d to make d the subject to find the required equation for des.
