Becky's speed is her distance travelled which is 30 km divided by her time travelled of 2.5 hours which gives her average speed of 12 km/hour which is a quite good speed if she was say riding a bicycle and which would give her a good aerobic workout.

We calculate first the initial pressure of the gas.
P = nRT/V
= (0.215 g/mL)(1 mol/16 g)(0.0821 L.atm/mol K)(302K)
= 0.333 atm
Using the relationship between the pressure and temperature,
P1/T1 = P2/T2
Substituting the known values,
(0.333 atm) / (29 + 273) = P2/(950)
P2 = 1.05 atm
