Fielder catching a projectile

A cricket ball is hit from an origin $O$ at ground level, on a horizontal oval. Its position at time $t$ seconds is given by $\tvec{r}(t) = 12t\,\tvec{i} + \left(19.6t - 4.9t^2\right)\tvec{j}$, where $t \ge 0$, $\tvec{i}$ is a unit vector in the forward direction and $\tvec{j}$ is a unit vector vertically up. Displacement components are measured in metres.

A fielder is located at the position $60\tvec{i}$ when the ball is hit.

The distance, in metres, the fielder must run to catch the descending ball at a height of 1.5 m above ground level is closest to
