Problem

A cyclist travels such that his velocity remains constant at

6\,\text{m/s}

for the first

4\,\text{s}

and then increases uniformly to

14\,\text{m/s}

in the next

3\,\text{s}

. Find the total displacement covered in the

7\,\text{s}

. a)

60\,\text{m}

48\,\text{m}

54\,\text{m}

42\,\text{m}
